QJM series hydraulic motor's structure principle:
The QJM hydraulic motor's oil distribution shaft is rigidly connected with the rear cover. The rotor block uses the oil distribution shaft as
radial support and employs a stator spherical rollaway nest and steel ball as axial support. The rotor's output shaft is an internal spline,
and the rotor block is floating. The oil distribution shaft is rigid, allowing the use of steel pipe connections for oil inlet and outlet.
